Re: GETTING ERROR IN XDECO

most probably You are trying to assemble thru the standard assembler a program meant to be assembled/linked/executed under the ASSIST learning tool, without using the proper libraries!(I wonder if it will work outside the ASSIST environment )

cheersenricoWhen I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,so that I am sure that the information requested can be reached with a very small effort

As Enrico says, you need the Assist Assembler or at least macro libraries and other capabilities to allow Assist macros to be used with IBM's High Level Assembler. Your course instructor should provide this information as it is site dependent.

Not only that, but your method to establish addressability in your program is incorrect, and will cause your program to fail.
